9Claiml;

determined length of the sensitized strip has been moved and exposed.

Another object of the instant invention is'the contemplation of such a. camera, wherein is incorporated severing means .for the vsensitized strip which is simultaneously brought into action as the advancing means is halted, and also asv the circuit leading to the source of power for all parts of the camera is broken by the opening of a switch that is in juxtaposition with one of the members forming a part of the aforesaid severing structure.

One of the important aims of this invention is to provide a mechanical camera of the nature above mentioned, having means for performing the function set down that is exceptionally simple, durable and strong; such means Abeing of a nature that complicated parts are not present and likelihood of maladiustment is eliminated.

With these broad general objects in view, the invention will now be described by reference to thev accompanying drawings, wherein the preferred embodiment of the invention is illustrated, and wherein: i o

Any suitable cabinet, not here the same being light-tight so that when the length of sensitized strip is expelled from the structure here disclosed, the same may be developed and otherwise handled immediately prior to delivery'to the subject or customer.

Base I4 carries the vertically disposed plates I6, Il and 20, to which is adjustably aiiixed front plate 22, which in turn supports lens 24 and all the necessary component parts thereof that will, permit presenting the proper opening. Such parts are usually called the iris diaphragm.

In practice, lens 24 is focused by moving front plate 22 toward and from the plane through 20 which passes sensitized strip 26. When the focal point is determined, nuts 28-are moved to position along screw threaded pins 2li and further attentiontothemechanisminthisregardisobviated. n

Proper exposure is made through the me of a motor-driven, revolving shutter $2 having an aperture 34 formed therethrough as shown in Fig. 3, which aperture may be increased and decreased in size by an adjustable shield 36 in order to ob- 30 tain the desired exposure time. The axis of shutter l2 is positioned concentrically with'the center of lens 24 and as shutter 32 is revolved, light is permitted to 'pass to sensitized strip 2B only during the time that aperture I4 is in front 85 of lens 24. Inpractice, while lens 24 is closed against projecting light against strip 2B through` case 3l. the subject is caused to change his pose. In this manner the mechanism of the camera s need `not. be `stopped until the predetermined number of exposures are made.

A motor 4l powers the moving parts of this camera,.and thesameis belted as at 42 to a drive pulley 44. carried by shaft 46, which has a worm gear4lkeyedtheretothatisinmeshwithgear45' I2 is mounted. Rotating shaft Il will rotate shutter l2 and power from motor 40 is trans- 55 mitted to shutter I2 through the parts just set forth.

As shutter l2 ls rotated, each complete revolu# tion thereof is indicated to the operator through theuse of anaudible signalinthe form of a'bell 80 I 82, theclapper 84 ofwhich isstruckbytrip 88 each time shutter 82 completes a reimlution. Relative location of trip 88 and aperture 84 may be altered so that the signal is sounded immediately after exposure is made in order to give'the maximum amount of time for reposing the subiect.

As shutter 82 is revolved. it is necessary to periodically advance sensitized strip 28 an amount sumcient to present a new une area thereof within case 88. This action is caused by the next described mechanism which is powered by motor 48. Shaft 88 is rotatably supported by plates I8 and I8 and carries, near one end thereof, a. ratchet wheel 18, wherein is formed a predetermined number of teeth 12 engageabie by dog 14 which is pivotally mounted upon pin 18 connecting link 18 and link 88, as shown in Figs. l and 2. Thus the pivotally mounted end of dog 14 may be moved around the axis of shaft 88 because of link 88. '11o so move dog 14 and cause the same to advance wheel 18, link 18 is pivotally secured to lever 82 which, in turn, is supported by shaft 82 and pinned thereto as shown at 84, Fig. 2. Pintle 88 joining link 18 and lever 82 travels around shaft 82 and in so doing reciprocates dog 14 so that it will periodically advance wheel 18. Thus periodic rotation is imparted `to shaft 88 which transmits such movement to drum 88 that is mounted thereon at the opposite end thereof. It is over this drum 88 that strip 28 from the roller 88, which has an idler 82 adjacent thereto for precluding objectionable unwinding. This roller 82 is carried by pivotally mounted arm 84 and tautness on the part of strip 28 is further insuredbytheuseofgearinmeshwithpinion 88. the latter having engagement with drum 88.

'Ihe pitch diameter of gear 88 is the same as the diameter of drum 88 and, since gear 88, shaft 88, and drum 88 rotate together, a feeding of strip 28 is caused which will preclude buckling or other objectionable action on the part of said strip 28. Roller |88, positioned diametrically opposite pinion 88, has a connection therewith through the medium of spring |82 which may be of proper tension and changed to suit the nature of the stock used. Pivotally mounted arms |84 and |88 carry pinion 88 and roller |88 respectively. Four advancing steps are imparted to strip 28 through the aforementioned structure, and since it is desired to sever the length of strip so advanced after it has been moved forward four times, means for stopping such advancing movement is provided in the form of control disk |88. This disk is securely mounted to shaft 88- between ratchet 18 and drum 88. It is preferably carried between -plates I8`and I8, as shown in Fig. 2. Disk |88 rotates with shaft 88 and hasy diametrically opposed notches ||8 formed therein for the purpose of receiving pin ||,2, carried by setting arm I4 that is pivotally mounted upon shaft |8, supported by plates I8 and I8. The lower end of arm I|4 is so pivotally mounted, while the upper end thereof is urged toward disk |88 by spring I I8.

A shoulder |28 is formed on arm ||4 which engages a switch |22 to move contact points thereof |24 and |28 toward and from each other to open and close the electrical circuit built into the camera. Obviously, when pin I|2 is in engage Vin Fig. 8, switch |22 will be closed and motor 48 wilistartforthepiuposeofdrivingallthehereinbefore mentioned parts.

A plate |28 is freely and, pivotally mounted upon shaft 88 immediately against one side of disk |88. vA spring |38 urges plate |28 against stop |82, whereby to cover or close both notches I|8. This precludes the entrance of pin I I2 into notches I I8 until plata |28 is forced from over notches` I I8, which force must be sumcient to extend spring |88. Projections |34, integral with plate |28, lie beyond the annular periphery of disk |88 and when pin I I2 strikes projection |34, movement of plate |28 is stopped as rotation of disk |88 continues to a point where pin I2 snaps into the adjacent notch I I 8. Obviously, this movement on the part of arm II4 will immediately open switch |22 and stop motor 48.

While disk |88 rotates to move one notchV I I8 around to aposition where pin I I2 will snap into the diametrically opposite notch, ratchet wheel 18 is being advanced four steps by dog 14. and the associated parts. Therefore, when four exposures have been triade,k the mechanism will stop.V

Arm II4 carries bar |38 that extends through opening I 88 in plate i8 to' support knife |48 which is siidablyg mounted as shown in Fig. ll)r to and froma position where the path of travel of strip 28 is -intersected A shearing action against edge |42 takes place and the length of strip 28 just previously fed through case 38 will be severed from the remaining portion thereof. This severing action takes place as arm |I4 snaps into the position shown in Fig. 6. 'Ihus a vering action and a circuit-breaking action simultaneously-occurs.

The changing of control disk |88 so that the distance between notches I I8 b'y way of the annular periphery of said disk is altered 'will vary the number of exposures made during a half revolution of shaft 88. Similar alterations in sizes, relations and resulting functions might likewise be made in other parts of the camera without departing from the spirit of the invention.

Fig. ll diagrammatically illustrates the electrical circuit and manner in which switch |22 controls the action of motor 48. Current from supply line 288 reaches switch |22 by way of wire 282 and, when contact points |24 and |28 are together, conductor 284 carries the current to motor 48 from where wire 288 completes the circuit back to main line 288.

The operation of the camera mechanism embodying the features of the invention has been made clear during the course of the specification, l and while but one form of the invention has been f shown and described, it is not desired to be limited thereby except as required by the appended paratus for periodically advancing said strip past said knife; common means movable tomechanically lock said advancing apparatus and to simultaneoushr actuate the knife to severvsaid strip after a predetermined length vof the same has moved past said knife; and Ia switch having connection with said means for opening the motor circuit when said means moves to actuate the knife and lock the advancing apparatus.
